Beer may be empty calories, but do you know how many? In the not-too-distant future, we may get a reminder on every bottle. In Europe, top beer makers including Heineken and Carlsberg have just agreed to start putting nutrition labels on their products—and experts predict the trend will headed to the states next, according to The Wall Street Journal.

Do you know how many calories are in a 12-ounce can or bottle of your favorite brewski? Test your knowledge with our quiz! Keep in mind that the more alcohol a brew contains, the more calories it tends to have—and alcohol by volume (ABV) can vary by label within a category.
